| Abstract | Alzheimer's disease (AD) is a chronic and multi-factor-induced neurodegenerative disorder. The development of a single-target treatment strategy for AD has not been successful. Shengmai-San (SMS), a traditional Chinese medicine containing multi-active components, has been reported to be effective for treating AD. However, the mechanism of SMS is still unclear, and as a multicomponent combination therapy, there is a lack of appropriate evaluation. Thereby, metabolomics was applied to investigate the multi-target intervention of SMS by monitoring the fold changes of metabolites in serum. An AD model was successfully replicated by treating rats with oral aluminum chloride (AlCl3) and an intraperitoneal injection of D-galactose (D-gal) for 105 days. The intervention group was treated with SMS during the whole modeling process. The results of classical experiments showed that SMS could alleviate Aβ1–40 deposition, protect neurons in the CA3 region of the hippocampus and improve spatial learning and memory impairment compared with the model group. Based on these curative effects, a metabolomics study was implemented using the UPLC-Q/TOF-MS method. A heatmap of AD-associated metabolites (P < 0.05) was set up to target the most relevant metabolic network and to evaluate the comprehensive effects of SMS. Based on this AD-associated metabolic network, the total regulation-of-metabolites’ coverage rate of SMS was 51.35% and the gross metabolites’ recovery proportion was 72.32%. Lipid peroxidation was the main mechanism of SMS intervention in AD, including inhibition of the generation of linoleic acid hydroperoxides, such as 13-HPODE, 9-HPODE and 9-OxoODE. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
